The present invention relates toimprovements in a combined container and dispenser, and it consists of the combinations, constructions and arrangements hereinafter described and claimed.

In mixing paints and other colored materials, it is necessary that the exact quantities of the different colors be mixed together in order to arrive at the desired color. This is especially true where the color of a certain paint is to be matched. The principal object of my invention is to provide a combined container and dispenser which will hold a predetermined or measured quantity of material and which will dispense all of the material therein so that the operator will know that when the dispenser has been moved through the tube, a predetermined measured quantity of material will be expelled.

A further object of my invention is to provide a device of the type described which is simple in construction and durable and efficient for the purpose intended.

Other objects and advantages will appear in the following specification, and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a part of this application, in which:

Figure 1 is a longitudinal section through the combined container and dispenser and illustrates how the container cap can be removed and how the dispenser can be moved toward the open end of the container or tube; and

Figure 2 is a longitudinal section through the tube with the cap removed and the dispenser moved to a position where its outer end lies flush with the mouth of the tube.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the appended claims without departing from the spirit of the invention.

The tube is indicated generally at A and has a cylindrical wall I that may be made from any material desired, such as glass, plastic, metal,

the cap will provide a'double seal for the tube contents. It is possible to provide a cap'with a circular flange that' is receivable in the tube and then expand the cap at the juncture between the flange and cap' base for causing the expanded portion to contact with the tube wall and provide the double seal.

The rear end of the tube'is closed by a material dispenser which includes a disc 9 that has a flange Ill normally received in the groove 3 and sealed to the lip, flange and tube wall. The

' disc carries a flexible ejector plug II that constitutes the other part of the dispenser and the plug may be made out of any flexible material such as papencork, etc. The plug is preferably treated with wax, grease, or oil to permit it to slide readily in the tube and also to cause it to act as an air seal for preventing air from entering the tube and drying out the contents. The center of the disc 9 has a depression l2 for re ceiving a tool, such as a nail l3, for moving the dispenser consisting of the disc and the plug toward the mouth end of the tube. The tube contents may be in a liquid state or a semi-liquid and may even be a paste or a powder.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood.

When it is desired to remove the cap in order to expel the tube contents, the nail I3 or other tool may be applied to the cap in the manner illustrated in Figure l to pry the cap from the tube. Should any of the pigment in the tube adhere to the cap, it is scraped off into the tube in order that all of the tube contents be retrieved. The contents of the tube are now forced therefrom by moving the plug II from the position shown in Figure 1 into that shown in Figure 2. Since the plug is made of a flexible material, it will have its front end Ila compressed slightly so that the outer surface of this end will lie flush with the mouth of the tube. The plug will thoroughly wipe the interior surface of the tube clean of all pigment and therefore when the plug reaches the mouth end of the tube, all of the contents will be removed. It is this entire removal of the tube contents which is the vital feature of my invention.

I claim:

1. A combined container and dispenser for holding a premeasured quantity of material and for delivering all of the material for immediate use, comprising a cylindrical casing wall open at both front and rear, a' removable cap closing the front end of the casing wall, and a movable dispensing plug normally closing the rear end and having a wiping engagement with the casing wall of suificient length to prevent the plug from tilting when it is manually moved, said cylindrical casing wall, cap and plug forming the container for housing a measured quantity of materiahsaid plug being lightly sealed to the rear of the casing wall so that the seal will be readily broken when an object is manually pressed against the plug for moving it, the front end of the casing wall having an inner edge that merges into the inner surface of the casing wall so that the plug when moved will wipe the casing Wall and eject all of the measured quantity of cylindrical member and contacting with the rolled edge and with the cylinder wall, the dispenser consisting of a disc having a flange initially sealed in the groove, and a plug made of flexible material secured to the disc, said cylindrical member, cap and plug forming the container for housing a measured quantity of material, said plug being movable by the disc to the mouth end of the cylindrical member after the cap is removed for yieldingly wiping the inner surface of the member for expelling all of the measured quantity of material from the membe for immediate use, said rolled edge acting as a stop for the plug and causing the plug periphery to contract upon striking the rolled edge so that the face of the plug can be brought flush with the plane of the mouth so that unobstructed access may be had to the plug end for removing any of the material that might adhere thereto, whereby all of the material is removed from the container for immediate use.
